2 Claims.

This invention relates to shipping cases or packages, and particularlyto such as contain canned goods. It is customary to ship canned goods inpacking cases, the walls of which are formed of corrugated paper orother more or less flimsy material and these walls do not offerresistance to external pressure on the case, as a result of which thebodies of the cans in the cases are frequently bashed in -and dented in'such a way that they are unsightly and more or less unsaleable.

One of the objects of this invention is to produce a shipping packagefor canned goods having simple means inserted in the case with the cansto attain a reinforcing effect and prevent, as far as possible, injuryto the cans from external pressure on the case. 'Ihe invention isparticularly applicable where two or more tiers of cans are packed intothe case, and one of the objects of the invention is to provide simple,inexpensive means capable of being packed into the box or case with thecans and operating to brace the side walls of the case between the topand bottom of the case, and also operating to brace and reinforce thevertical corners of the boit or case.

Further objects of the invention will appear hereinafter.

Ihe invention consists in the novel parts and combinations of parts tobe described hereinafter, all of which contribute to produce an emcientshipping package.

A preferred embodiment of the invention is described in the followingspecifications, while the broad scope of the invention is pointed out inthe appended claims.

In the drawing:

Fig. l is a plan of a shipping package of canned goods, embodying myinvention and showing one of the flaps of the cover closed and the otherap open; one of the open flaps is broken away. This View represents abox or case with the lower tier of cans within the same, and representsa horizontal partition wall broken away at an intermediate point.'

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1, butshowing the cans adjacent the side walls that are shown in section,broken away to further illustrate reinforcing stringers or angled piecesthat I employ in the corner of the box.

In practicing the invention, I employ a shipping case of the usual boxform having bottom and side walls. The top, bottom and side walls ofthis box have a certain degree of stiffness, but

lll

Jill

(Ul. 22g-ll 5) are of insumclent rigidity to prevent the cans from beingsubjected to damaging pressure through the side walls.

The cans that are packed into the case are arranged in tiers laidprogressively upon the bottom, and in the present instance I haveillustrated the invention as applied to a box or case which is merelydeep enough to accommodate two tiers or layers of the canned goods. Inaccordance with my invention, I provide a horizontal bracing partitionlocated between the tiers of cans, which partition substantially illsthe hori- Zontal cross section of the case. In addition to this, Iprovide means cooperating with this horizontal partition fordistributing its pressure against the side walls and for incidentallyreinforcing the Vertical corners of the case.

Referring more particularly to the drawing, l indicates a shipping caseof box form having a bottom il and vertical side walls il. rI'he bottomn 2 may be of a single piece of material, or it may be composed of flapstu., 2b, which are hingedly connected to the bottom edges of the sidewalls and which overlap each other to form a complete box.

'I'he cover of this box as illustrated has the same construction as thebottom. That is to say, it comprises two oppositely disposed flaps 42and two oppositely disposed flaps tb which are all folded down so as tooverlie each other when the box is closed for shipment. Within the boxor case, I pack a plurality of canned goods of any kind. The cans b arelaid as indicated in Fig. 1, so that they substantially fill the box orcase bali full, but before putting the cans in the case I provide thefour corners B of the case with reinforcing strips l. These strips maybe formed of stout cardboard, or similar material, and each stripcomprises a central web 8 and flanges d. At the junction between theflanges and the webs, the material is creased and offset to enable theanges to be folded against the side walls of the box to form a tube oftriangular cross-section having a space l0 within the same. This channelenables the material to bend readily without any danger of breaking.After the bottom layer of the cans has been put in place, I lay upon thesame a horizontal partition wall Il. This partition wall has cornerswith rounded edges I2 which fit against the outer faces of the webs 8 ofthe corner strips. The partition ll substantially fills the horizontalcross section of the case and it will be evident that if pressure isexerted upon the vertical side walls of the case, this pressure will beresisted by the partition wall ll, the

dit

rigidity of which substantially assists the side walls in resisting sucha pressure. In this way, unless the force is very great. the cans withinthe case will be protected against dents.

Furthermore, it will be evident that the strips I at the corners of thebox very substantially reinforce the corners and also operate to takethe pressure of the partition I I and distribute it over 'considerablearea on the inner faces of the vertical side walls.

The webs 8 may also be engaged by the sides of the cans, therebyassisting the side walls in holding the cans in place.

It will alsobev evident that the corner strips I and the horizontalpartition wall I I are very inexpensive and do not materially increasethe cost of the shipping case; at the same time they very substantiallyincrease the resistance oi' the case to external pressure on its sideWalls.

What I claim is: l

1. In a shipping package for holding a plurality of cans of canned goodsdisposed in tiers, the combination of a box-form shipping case having abottom and side walls of insufficient rigidity to prevent the cans frombeing subjected to a damaging pressure through the said side walls,

and a substantially horizontal rigid partition wall located between thetiers of the canned goods, substantially filling the horizontalcross-section of the case and bracing its side walls against externalpressure, and an angle-form corner strip disposed in each verticalcorner of the case ex- -tending past the said horizontal partition andengaging the edge faces of the corners of said partition wall, saidcorner strips operating to engage the faces of the adjacent cans, andalso operating to center the partition wall and distribute the pressureoi.' its edges against the corners of the case.

2. In a shipping package for a plurality of cans of canned goodsdisposed in tiers, the combination of a box-form shipping case having abottom and side walls of insuilicient rigidity to prevent the cans frombeing subjected to a damaging pressure through the said side walls, anda substantially horizontal rigid partition wall located between thetiers of the canned goods, substantially lling the horizontalcross-section of the case and bracing its side walls against externalpressure, and angle-form corner strips disposed in the vertical cornersof the case engaging the edge faces of the horizontal partition, eachcorner strip having fianges resting against the inner faces of the sideWalls and having a web connecting the iianges, engaging the faces of theadjacent cans in said tiers and extending across the vertical angles ofthe case, said partition having rounded corners engaging said webs, saidcorner strips operating to center the said partition wall and protectthe corners of the case from the same.
